Engine Replacement as a Way to Control Air Pollution
My idea for state and federal air quality bureaus to get better control of the air quality in their locales would be an engine and transmission replacement program for older vehicles. Many of these vehicles are owned by low and middle income drivers, who cannot afford newer and less polluting autos; replacing the engines of these autos would be an economical way to keep air quality from deteriorating. One suggestion is to provide a certain percentage to car owners, such as 75% of the costs to replace these parts with rebuilt ones, if their vehicles have not passed state air tests.

Reward: Not having to go into the whole for a new car, and cleaner air.
